I really still not understand how the concept of this gluster work.
I have a plan to building cluster for storage server. The idea is, if the capacity of the current storage cluster system will empty i just add the new server with full storage and so on. So i can get more new capacity after adding a new server on the fly (maybe it could be Like youtube.com storage server). Can I do this with glusterfs ?
Please help me to do this, and correct me if i have something wrong here and sorry for my bad english.

Okay, finally i was succes to make the glusterfs works for me.
After i try the configuration, i still not looks that glusterfs still not able to combine all resources harddrive be one unity storage.
But i still have the questions here. Are the glusterfs can combine all resources harddrive on another server to be one unity ? Is there anybody can help me how to do this ?
Thank you for your response.

Thanks for your reply. I am glad you reply my question. Falko, can you help me what is it mean about for this log :
"Volume 'bricks', line 49: type 'cluster/unify' is not valid or not found on this machine" ?
When I try to make unify, but the system always show that log.
Let me shared my client configuration here ;

Okay, now i know what is mean of "type 'cluster/unify' is not valid or not found on this machine".
I try to debug, and it try to load the "unify" module on my system. But the file is not there. So i try to search the file with "locate unify.so" and copy it to the directory that glusterfs wants. And it working.
But I still have an issue here.
I don't know how to make the script configuration for "ioctl".
I still get the message error is ;
"glusterfs: end of file- Inappropriate ioctl for device.
Is there anybody know how to make the script for this ?
